Benzalkonium+gentamicin
About Benzalkonium+gentamicin
Benzalkonium+gentamicin is a sterile prescription drop used to treat bacterial infections in the eyes and ears. It contains an antibiotic that stops the growth of bacteria causing discomfort, redness, or swelling in these sensitive areas. By clearing the infection at its source, this medication helps restore comfort to your eyes or ears.
For the treatment to be successful, you must use Benzalkonium+gentamicin regularly and at evenly spaced intervals as directed by your healthcare professional. Do not skip doses or stop using the drops early, even if your symptoms improve, as the infection could return. You can use these drops independently of your meals. While using this medication, practising good hygiene, such as washing your hands frequently and avoiding touching your eyes or ears, can greatly support your recovery.
Like many localised treatments, Benzalkonium+gentamicin may cause mild, temporary side effects such as a brief stinging or burning sensation right after application. Most people tolerate these drops well, but you should contact your doctor immediately if you experience severe irritation, swelling of the eyelids, worsening pain, or signs of an allergic reaction.
Do not use this medicine if you are allergic to gentamicin, benzalkonium chloride, or similar medications. Before starting, tell your doctor if you have a history of hearing issues or kidney problems or if you suspect you have a torn or ruptured eardrum. Using this medication in the ear when the eardrum is damaged can lead to serious inner ear issues.
Inform your doctor about all other eye or ear medications you are currently using, as space is required between different topical treatments to prevent them from washing each other out. If you are pregnant, planning to become pregnant, breastfeeding, or managing health conditions in an elderly patient, discuss the safety of this medication with your healthcare provider first.

Habit Forming
Diet & Lifestyle Advise
- Avoid contact lenses: Do not wear contact lenses while treating an eye infection. The preservative benzalkonium chloride can be absorbed by soft contact lenses and discolour them, and lenses can trap bacteria against your eye, delaying healing.
- Keep ears dry: If treating an ear infection, prevent water from entering your ear canal while showering or bathing. Avoid swimming until your doctor confirms the infection has completely cleared.
- Do not touch or rub: Avoid rubbing your eyes or scratching your ears. This can worsen inflammation and introduce new bacteria to the healing tissue.
- Practise clean habits: Wash your pillowcases, towels, and washcloths in hot water regularly to prevent reinfection.
Special Advise
- Use of Benzalkonium+gentamicin for prolonged may result in a new fungal eye infection (secondary infection). Do not use Benzalkonium+gentamicin for longer than prescribed.
- Benzalkonium+gentamicin should not be administered directly into the eye's anterior chamber.
- Benzalkonium+gentamicin must not be used in the ear if the eardrum is damaged in any way.
- It is advised to contact your doctor if the infection symptoms persist or worsen after two weeks of treatment.
- If you experience any purulent (pus-containing) discharge or your inflammation and pain increase while using Benzalkonium+gentamicin, please discontinue the use and consult a doctor.
Patients Concern
Disease/Condition Glossary
Conjunctivitis, also known as pink eye, is a condition in which the outer membrane of the eyeball becomes swollen and infected. There are typically three types of conjunctivitis: bacterial conjunctivitis, viral conjunctivitis, and allergic conjunctivitis. Common signs and symptoms include red-toned eyes with a thick discharge and intense itchiness. It is highly contagious and can spread from one person to another.
Otitis externa: It is a condition that causes inflammation (pain, redness, and swelling) of the external ear canal, which is the tube between the outer ear and the eardrum. Bacterial infections primarily cause it. Pseudomonas aeruginosa and Staphylococcus aureus are the most common bacteria that cause otitis externa.
FAQs
Benzalkonium+gentamicin is used to treat bacterial infections in the eye and ear, conjunctivitis (pink eye) and otitis externa (redness and swelling of the external ear canal).
Benzalkonium+gentamicin contains Gentamicin, an antibiotic which stops bacterial growth by preventing the synthesis of essential proteins required by bacteria to carry out vital functions. This prevents bacteria from repairing and multiplying. Thereby helping in treating ear and eye bacterial infections.
Prolonged use of Benzalkonium+gentamicin can lead to an overgrowth of other microorganisms, such as fungi, and the development of bacterial resistance.
Benzalkonium+gentamicin ear drops should be used with caution and only under a doctor's supervision if you have chronic otitis media (infection of the middle ear cavity) or a perforated tympanic membrane (a hole or a tear in the tissue that separates the ear canal from the middle ear). Let your doctor know if you have kidney disease, myasthenia gravis (neuromuscular disease), before using Gentamicin.
Never stop the treatment with Benzalkonium+gentamicin on your own, as the infection may come back again (relapse) if the prescribed treatment is not completely taken before stopping Benzalkonium+gentamicin.
You should avoid contaminating the applicator tip of Benzalkonium+gentamicin with material from the eye/ear, fingers, or other sources. Try not to share personal items or clothing until your eye or ear infections persist. Do not wear contact lenses, as they can exacerbate your eye condition. Additionally, avoid inserting cotton swabs and bobby pins into your ear, as this can worsen your ear condition.
Yes, Benzalkonium+gentamicin effectively treats bacterial eye and ear infections, such as conjunctivitis (also known as pink eye) and otitis externa (inflammation of the external ear canal). It effectively reduces inflammation and kills the bacteria, which helps improve symptoms. However, following your doctor's instructions for proper use is crucial to ensure its effectiveness.
If you forget to use Benzalkonium+gentamicin, use it as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue your regular schedule. Do not use extra drops to make up for the missed dose.
Like any medication, Benzalkonium+gentamicin may cause side effects, although not everyone will experience them. Common side effects include a burning sensation in the eyes or ears, ear pain, irritation upon application, and blurred vision. These effects are typically temporary and may subside shortly after use. If you notice any unusual or severe symptoms, contact your doctor immediately.
Benzalkonium+gentamicin should be stored in a cool and dry place, away from direct heat or sunlight. Keep the container tightly closed and out of reach of children. Do not freeze this medication.
No, you should not wear contact lenses while treating an eye infection. Additionally, the preservative benzalkonium chloride in the drops can be absorbed by soft lenses and cause discolouration. Talk to your doctor about when it is safe to wear your lenses again.
A mild, brief stinging sensation is common right after applying the drops and usually goes away within a minute. If the stinging is severe, causes continuous watering, or worsens over time, stop using the drops and talk to your doctor.
Even if the medication is formulated for both eye and ear use, you should never use the same bottle for both areas if you are treating active infections. Doing so can easily transfer bacteria from your ear to your eye or vice versa. Talk to your doctor if you need separate bottles.
The active antibiotic can sometimes be absorbed into the body in tiny amounts. If you are pregnant or planning to become pregnant, you should only use these drops if your doctor decides the benefits outweigh any potential risks. Talk to your doctor before starting treatment.
While the small volume in a single bottle is unlikely to cause severe poisoning, accidental ingestion can still cause stomach upset or irritation. If someone swallows this medication, contact a poison control centre or seek medical help immediately. Talk to your doctor if any unusual symptoms occur.
